Basically I need this while loop to perform 4 times
It will ask user for input then use that input in the nested if statements. (repeat 4 times)
The first prompt will show up and I am able to type an input.
but after that it just gives me an error.
and keeps pointing the error to "int userInput = scan.nextInt();"
I have no idea whats wrong with it. Can someone guide me? thanks
int count = 0;
while (count < 4 ) {
System.out.println(prompt1);
int userInput = scan.nextInt();
(some nested if statements here to do my task, they all have
count++ at the end)
}
Always check if the nextInt is available before asking for it :
if(scan.hasNextInt())
{
int userInput = scan.nextInt();
// do something
}
